AUGUST PERPENTE, OF NEW YORK, N. Y., ASS IGNOR TO HIMSELF AND MAX LANGGUTH, 0F HOBOKEN, NEW JERSEY.

lMPROVE MENT IN SHEET-METAL CANS.

Specification forming part of Letters Patent No- 17S.'462, dated J une 6, 1876; application filed March 9, 1876.

To all whom it may concern:

Be it known that I, AUGUST PERPENTE, of the city, county, and State of New York, have invented a new and useful Improvement in Sheet-Metal Cans, which improvement is fully set forth in the following specification, reference being had to the accompanying drawing, in which- Figure 1 represents a vertical central section. Fig. 2 is a plan or top view when the can is partly opened.

Similar letters indicate corresponding parts.

This invention consists in a sheet-metal can, the top plate of which is provided with a hole to receive a depressed sheetmetal cover, in combination with a convolute' flexible strip of sheet metal, which is soldered to the top plate of the can and to the disk, and one end of which is left loose, and made to overlap the other end, so that by pulling on this loose end the flexible strip can be readily detached, and thereby the disk is released, and the can is opened, and by replacing the disk the contents of the can can be protected against dust or other impurities.

In the drawing, the letter A designates a sheet-metal can, the top plate B of which is provided with ahole, a,for the reception of the sheet-metal disk 0. This disk is made saucer-shaped, as shown, so that the same, when placed into the hole a, will be retained in position; or the same result may be obtained by using a flat disk, and depressing the edge of the hole a, so as to form a recess for the reception of the disk.

With'the disk 0 and the top plate B is combined a convolute flexible strip, 1), of sheet metal, which is soldered to the top plate and to the disk. One end of this flexible strip extends over its other end, and is left loose, or only slightly fastened, so that it can be readily bent upward, and by pulling on this loose end the strip D can be detached, so as to release the disk and give access to the contents of the can.

By this arrangement the disk (J is left entirely intact, and it retains its original shape,

so that after the can has been opened and partly emptied its remaining contents can be protected against dust or other impurities by readjusting the disk 0 in the hole a of the top plate.

I am aware that a strip of metal has been used to secure the top to a sheet-metal can, such strip being soldered to the side of said can. This operation is difficult to accomplish without turning the can over on its side. In my can the strip can be conveniently soldered in the proper position while the can stands upright, and when the cover has been opened it can be easily replaced into the opening a, so as to protect the contents of the can.

I am also aware that a wire has been used for opening the can-top, said wire being soldered between the cover and the top plate of the can. In this device the wire is liable to work loose, so that the can opens and its contents are spoiled.

My strip of sheet metal overlaps a portion of the top plate, and also a portion of the cover. 'When soldered on, it effectually closes the joint between the cover and the top plate, and it is not liahleto work loose. I

What I claim as new, and desire to secure by Letters Patent, is-

A sheet-metal can with a central opening in the top, the depressed sheet-metal cover 0 adapted to tit the opening, and overlapping the edge of said opening, in combination with the annular strip D of sheet metal, overlapping the edges of the top plate and of the cover, and being soldered to the same, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand and seal this 2d day of March, 1676.

AUGUST PE'RPENTE. [L. s.]
